To my surprise, this tool settled my problem in a few minutes! I want to share my happiness with you who might have the same problem with me. The app is worth trying to copy dvd movies and import them into iphone 5 like me, or some other devices.
But only five minutes per DVD in trail version.

This great Mac DVD Ripper can rip any DVD movies to hard drive with ease on Mac! Support any DVD formats to be ripped to AVI, MP3, MP4, etc, enjoy DVD movies anytime and anywhere without inserting DVD disc.
The flaw I found is that the standard edition lacks editing features and picture quality cannot be adjusted.

Great tool with fast speed and great output image quality. There are a couple of features that would make great additions, but it is pretty much perfect for what I'm looking to do at the moment!
However, no drag and drop feature, it is a pity.

This DVD ripper is awesome! Very efficient, I can watch anywhere on all my devices because it rips in all formats. Now I can keep my collection of dvd movies with me wherever I go.
The weak point is lacking direct support; only technical support is available via email.

The app is pretty much perfect for what I'm looking to do at the moment! I really appreciate its fast ripping speed so that I don't need to spend time waiting for the conversion.
On the other hand, the software has limited editing tools, and its preview function seems a bit useless.

It is miraculous! I’m a DVD fan, but it is not an easy thing to fine the one you want from great number of DVD collections. This app gives me a great hand. With it, I back up all of my DVDs to my macbook and now whenever I want to watch some of them, I can easily pick it out. What I must say is that the ripping speed of the app is amazing. It is the liberator for us DVD fans.
Its weak point is dull color. Hope its color would be improved.
